8 Claims.

The present invention relates generally to scribers. More particularlythe invention relates to that type of scriber which is designed for usein scribing or scoring linoleum type material so that the latter may becut by a knife or like sharp edged tool in connection with laying orapplication thereof.

One object of the invention is to provide a scriber of this type whichbecause of its specific design is so adjustable and manipulable that itis capable of making substantially all conventional types of scribes orscores.

Another object of the invention is to provide a scriber whicheflficiently and effectively serves its intended purpose and may bemanufactured at a low and reasonable cost.

A further object of the invention is to provide a scriber which is animprovement upon previously designed tools or scribers for the samepurpose and comprises as the main parts thereof a bar having atransversely extending set screw retained needle at one end thereof anda block which is mounted for sliding movement longitudinally of the barand embodies means for releasably and adjustably holding a secondscribing needle and in addition an arm which is disposed under andparallel to the bar and has a rounded or cylindrical guide element atits outer end and also a longitudinal centrally disposed slot for theneedle on the bar. 7

Other objects of the invention and the various advantages andcharacteristics of the present scriber will be apparent from aconsideration of the following detailed description.

The invention consists in the several novel features which arehereinafter set forth and are more particularly defined by claims at theconclusion hereof.

Figure 9 is a fragmentary perspective view of the scriber of Figure 8. v

The scriber which is shown in Figures 1 to 7, inclusive, constitutes oneform or embodiment of the invention. It is adapted for scribing orscoring linoleum type material in connection with laying or applicationof the latter, as hereinafter described, and comprises as the main partsthereof an elongated bar l2, a side block l3, and and arm I4.

The bar 12 is substantially square in cross section and is preferablyformed of metal so that it is rigid. A scribing needle I5 is carried byand extends transversely with respect to one end of the bar, as shown inFigure 1 and serves as a scribing or scorin'g'mediumin connection withcertain uses' of the scriber. This needle is pref erably in the form ofa steel phonograph needle and has one end thereof tapered to a sharppoint for scribing purposes. The other end of the needle I5 issubstantially cylindrical and fits slidably in a transverse bore H5 insaid one end of the bar l2. The needle is slidable transversely of thebar for adjustment purposes and is releasably held in its variousadjusted positions by means of a set screw II. The latter extendsthrough a hole I8 which is internally threaded and extends between andintersects the bor I6 and the adjacent end face of the bar I2. When theset screw is loosened or withdrawn from the internally threaded hole I8the needle I may be shifted or slid transversely of the bar in order tospace the point thereof any desired distance from the bar. After thedesired or proper adjustment of the needle the set screw is adapted tobe tightened in order fixedly to secure the needle I5 with respect tothe bar.

The slide block I3, like the bar I2, is preferably formed of metal. Itis mounted on the bar so that it is slidable from one end of the latterto the other and is composed of a U-shaped piece I9 and a strip 20. TheU-shaped piece I9 comprises a cross-Wall 2| and a pair of side walls 22.Said side walls are formed integrally with and project in the samedirection from the side margins of the cross-wall 2|. The strip 29 fitsbetween and extends lengthwise of the free side margins of the sidewalls 22, that is, the margins which are remotely disposed with respectto the cross-wall 2|. It is secured in fixed relation with the U-shapedpiece I9 by way of a pair of pins 23 and forms with such side walls andthe cross-wall 2| a slideway 24 for the bar I2. This slideway issubstantially the same as the bar as far as cross-sectional shape isconcerned and permits of relative longitudinal sliding movement of thebar and slide block. The pins 23 extend through and. are in drive fitrelation with registering holes in the strip 20 and the side walls 22 ofthe U-shaped piece I9. The slide block I3 is releasably secured in thevarious positions into which it is slid or adjusted by means of a setscrew 25. This screw, as shown in Figures 1 and 3, extends through aninternally threaded hole 26 in the cross-wall 2| of the U-shaped pieceI9 and has a wing type outer end 21 for gripping purposes. When the setscrew 25 is loosened or unscrewed the block I3 is released and the slidebar and block are thus capable of being slid one relatively to theother. The end of the strip 20 which faces in the direction of thescribing needle I5 projects beyond the adjacent end face of the U-shapedpiece I9 of the block I3 and forms a guide element 28 for the scriber.This element is substantially semi-cylindrical as far as conformation isconcerned and is adapted. as hereinafter described, to be brought intoengagement with an edge of a linoleum type piece When the scriber isused to scribe or score such piece in connection with the cutting of astrip therefrom. A slight distance inwardly of the guide element 28 thestrip 20 of the slide block I3 is provided with a transversely extendingbore 29 for a second scribing needle 39. This bore extends parallel tothe side walls 22 of the U- shaped piece I9 and is in transversealignment with the scribing needle I5. The needle 3|! is preferably ofthe same type and design as the needle I5 and the cylindrical endthereof is adapted to be releasably held in the bore 29 by a set screw3| which, as shown in Figure 3 of the drawings, extends through alignedinternally threaded holes in the strip 23 and one of the side walls 22of the U-shaped piece of the slide block. When the needle 33 is in itsoperative position the point thereof extends in the same direction asthe point of the scribing needle I5. When the set screw 3| is loosenedor released the needle 30 may either be removed from the bore 29 or itmay be shifted longitudinally into any desired adjusted position.

The arm I4 is formed of a fiat metallic strip and extends parallel tothe bar I2. It is approximately half as long as the bar I2 and one endthereof fits flatly against and is suitably secured to the outer face ofthe elongated strip 29 of the slide block I3. The other or outer end ofthe arm is disposed in opposed relation with the needle carrying end ofthe bar I2 and has a longitudinally extending centrally disposed slot 32through which the pointed end of the scribing needle I5 projects. Asshown, this slot extends from the guide element 28 to a point slightlyinwards of the outer end of the arm I4. The elongated strip 20 of theslide block serves to space the arm from the bar I2 a sufficientdistance to permit linoleum type material of conventional or standardthickness to be inserted therebetween. The arm I I ,is preferably thesame in width as the U-shaped piece I9 of the slide block I3 and itsinner end edge is flush with the adjacent end edge of the slide blockI3. The slot 32 accommodates the scribing needle I5 in connection withrelative sliding movement of the bar I2 and the slide block I3. Theextreme outer end of the arm I4 is tapered 0r wedgeshaped, as shown inFigure 1, and embodies at the tip thereof a rounded or cylindrical guideelement 33. This element extends transversely with respect to the armand is located or disposed on what may be termed the under face of thearm. It projects in the same direction as the pointed ends of thescoring needles I5 and 30 and serves in several capacities in connectionwith use of the scriber.

The scriber of Figures 1 to 7, inclusive, has many capabilities of useand is adapted to make substantially all conventional types of scribesor scores. V

Figure 4 shows a piece Pv of linoleum type material on a floor F withone edge thereof in abutment with the baseboard B of a wall W, andillustrates the manner in which the scriber is usable when it is desiredto score the piece in connection with the application of a border striparound the margin thereof. In connection with this specific use of thescriber the set screw 25 is loosened and the bar and block are slidrelatively to one another until the scribing needle I5 is spaced fromthe guide element 33 a distance corresponding to the desired width ofthe border strip. After proper adjustment, the set screw 25 is tightenedso as to lock the slide block and bar in fixed relation. Thereafter thescribing needle I5 is adjusted or set sothat the point thereof projectsslightly beneath the bottom face of the guide element 33. In the use ofthe scriber under consideration, the second scribing needle 29 is notused. In using the scriber the bar I2 is positioned perpendicular ornormal to the baseboard B and is shifted or manipulated so as to bringthe guide element 33 into abutment with the lower margin of the board.When the guide element is so positioned and the pointed end of thescribing needle I5 is in engagement with the top face of the piece Psuch needle is disposed from the baseboard B a distance corresponding tothe width of theborder strip. After the aforementioned steps the scriberis shifted sidewise with the guide element 33 at all times in abutmentwith the baseboard B. During such shift or movement of the scriber theneedle I5 causes a scribe S in the top face of the piece P. Aftercompletion of the scribe the piece P is out along the scribe and the.strip which is outwardly of the latter is removed and the de'-' siredborder strip inserted and mounted in place. By adjusting the slide blockand bar relatively to one another so as to move the scoring needle Ieither towards or away from the element I5 the scriber may be set so asto make border strip scribes of any desired width.

Figure 5 shows a piece P of linoleleum type material on a floor F withone edge thereof in abutment with the base portion of a wall W and showsor exhibits the manner in which the scriber is usable when it is desiredto scribe the piece P in connection with the application of an insetborder strip inwardly of the edge of such piece. In connection with thisspecific use of the scriber, the needle 30 is first inserted into thebore 29 and is adjusted and set in such manner that the pointed endthereof projects a slight distance beneath the bottom face' of therounded or cylindrical guide element 33. Thereafter the slide block andbar I2 are slidably adjusted with respect to one another so as toposition the scribing needle 25 at the desired distance from the needle30. After proper setting of the two needles the scriber is placed on themargin of the piece P in such manner that the bar and arm extendperpendicularly to the wall W and the guide element 33 is in abutmentwith the base portion of such wall. After proper positioning ormanipulation, the scriber is moved transversely or laterally while theelement 33 is at all times in abutment with the wall W. During suchshift the needles I5 and 30 form scores S and SS in the top face of thepiece P of the linoleum type material. These two scores are spacedequidistantly apart and are in parallel relation with the wall W. At theconclusion of the scoring operation the piece P is out along the scoresS and SS" and the intermediate strip is removed and the desired borderstrip is substituted therefor.

Figure 6 of the drawings shows a floor F with a piece P" of linoleumtype material on the floor and a second piece of linoleum type materialPP with one margin thereof. in overlapped relation with the margin ofthe piece P" and illustrates the manner in which the scriber is usableto apply a scribe or score to the over"- lapping margin of the piece PPin connection with cutting of such margin in order to produce an evenseam between the two pieces in connection with laying or application ofthe pieces with respect to the floor F". In connection with thisspecific use of the scriber the second scribing needle 30 is removed andthe bar I2 is manipulated into a position wherein the scribing needle I5is disposed over and in alignment with the inner portion of the guideelement 33. Such needle I5 is adjusted or set so that the point thereofspaced from the top face of the arm M a distance slightly less than thethickness of the piece PP" of linoleum type maerial. After the foregoingmanipulation or adjustment; the scriber is placed in the position shownin Figure 6. In such a position the arm I l overlies the lapped marginof the piece P and the inner portion of the guide element 33 abutsagainst the edge of such margin. As soon as the scriber is in properposition it is shifted laterally, that is, in a sidewise manner andduring such shift the needle I5 makes a scribe in the top face of thepiece PP" of linoleum type material. Because of the action of thescriber, such score is in exact alignment with the edge of the lappedmargin of the piece P. At the COIICIHSIODzOf the scoring operation thepiece P is out along the score by way of a knife or. any othersharp'edged instrument. Upon: removal of the severed, marginal part orportion the piece PP" is pressedagainst the floor F into a positionwherein the edge thereof is in abutment with the contiguous edge of thepiece P. By properly using the scriber it is possible to make a perfectseam between the two pieces P and PP".

Figure 7 shows a table T with a piece P on the top thereof and shows themanner in which the scriber is usable to score the margins of the piecein connection with trimming or cutting of the piece to fit the tabletop. In connection with the specific use of the scriber underconsideration the bar I2 is adjusted or shifted so as to position thescribing needle I5 in alignment with the outer portion of the guideelement 33 and is then set by tightening the screw 25. The needle I5 isthereafter adjusted or set so that the point thereof is disposed overthe arm I4 a distance slightly less than the thickness of the piece P'of linoleum type material. After proper setting, the scriberismanipulated so as to bring the needle carrying end of the bar I2 and theouter or projecting end of the arm I4 in straddled relation with one ofthe projecting margins of the piece PP'. Thereafter the scriber isshifted inwards until it is arrested by abutment of the guide element 33with the adjacent edge of the table top. At the conclusion of this stepthe scriber'is shifted sidewise and as the result of the action of thescribing needle I5 produces or forms a scribe S in the top face of thepiece P. This scribe is in the same plane as the subjacent edge of thetable top and forms a guide line for the knife or other instrument whichis used to sever the projecting marginal portion of the piece P.

The scriber is capable of being used in ways other than thoseillustrated in Figures 4, 5, 6 and '7. For example, if it is desired tocut a border strip of uniform width from a straight edged piece oflinoleum or like material the scribing needle by way of a relativeadjustment of the bar I2 and the slide block is positioned from theguide element 28 a distance equal to the desired width for the strip.Thereafter the scriber is positioned so that the needle equipped end ofthe bar and the projecting end of the arm arein straddled relation withthe margin of the linoleum piece and is then shifted inwards in order tobring the guide element 28 into abutment with the adjacent edge of thepiece. When the scriber is maintained in such position and is shiftedlaterally or sidewise the needle I5 serves to make a scribe or score inthe piece at a fixed or uniform distance from the adjacent edge of thepiece. By cutting the linoleum piece along the score a strip of uniformwidth is obtained. If it is desired to make a scribe a comparativelygreat distance from a wall the bar I2 is reversed. Because the scriberhas provision for retaining in spaced relation two scribing needles itis possible to make circular scribes or scores with the scriber whendesired. To make a circular scribe the needle 30 is used as a centerpoint and the needle I5 after adjustment the proper or desired distancefrom the needle 30 is swung around the latter in such manner as to makea score on the face of the linoleum type material. The scriber ofFigures 1 to '7 inclusive, is simple in design and hence may bemanufactured at a low and reasonable cost. It

is so designed that it may be used expeditiously and efficiently andeffectively fulfills its intended purpose. By having the guide elements28 and 33 rounded as far as conformation is concerned they roll or slidereadily when in use.

The scriber which is shown in Figures 8 and 9 of the drawingsconstitutes another form or embodiment of the invention. It comprises abar 2l2, a slide block 213 and an arm 2M and with the exception of thearm is the same in design and construction as the scriber of Figures 1to '7, inclusive. The bar 2i2 carries at the operating end thereof ascribing needle 2I5. This needle extends transversely of the bar and isaxially or longitudinally adjustable. The arm M4 is fixedly secured tothe outer or under face of the elongated strip of the slide block 2l3and is like the arm I l of the scriber of Figure 1 except that the outerextremity thereof is bent or doubled back to form a hook 214*. This hookis provided at its extremity with a rounded or cylindrical guide element233. The latter extends in the same direction as the scribing needle 215and with respect to function and operation is analagous or similar tothe element 33 of the Figure 1 scriber. The arm 214 is provided with acentrally disposed longitudinally extending slot 232 which is adapted toreceive the point of the needle M5 and extends from the slide block 213to the bend of the hook 2W. The scriber of Figures 8 and 9 is adaptedprimarily for use in scoring the upper margin of a linoleum type pieceP" in connection with the application of the piece to a wall W having apreviously applied linoleum type border strip or piece PP" along theupper portion thereof. In using the scriber of Figures 8 and 9 in thecapacity just mentioned the bar 212 and the slide block 2|3 arerelatively adjusted or set so as to bring the scribing needle 2 l 5 intoalignment with the outer portion of the guide element 233. Thereafterthe hook 2H1 at the outer end of the arm H4 is hooked around the uppermargin of the piece P"" and the scriber is then raised in order to bringthe outer portion of the element 233 into abutment or engagement withthe lower edge of the piece PP"". After such procedure the scriber isshifted sidewise or laterally in order to form a scribe which is indirect alignment with the bottom edge of the piece P". When the piecePP"" is cut on this scribe and the scrap removed from it, the upper edgeof the piece P"" will fit flatly against the bottom edge of the piecePP" and form an acceptable seam. The scriber of Figures 8 and 9 isadapted for use in certain scribing work which cannot be easilyaccomplished by the scriber of Figures 1 to 7, inclusive. The guideelement 233 is provided at its inner end with an externally threadedstem (not shown). This stem is adapted to fit in any one of a group orset of internally threaded holes 233 in the inwardly extending portionof the hook portion of the arm 2M. The holes coact with the stem to forman adjustable connection whereby the element 233 may be securedreleasably in different adjusted positions with respect to the hook. Insome instances it is necessary to have the element disposed near thebend of the hook. In such cases it is only necessary to unscrew theelement and then mount it in fixed relation with any desired hole byscrewing the stem thereof into such hole.

The invention is not to be understood as restricted to the details setforth, since these may be modified within the scope of the appendedclaims, without departing from the spirit and scope of the invention.
